How to add information of spouse is separated and won't provide the information?

[Fabbasi]

I am separated from my spouse and he won't provide information such as his net income or how much he paid for tuition

You can enter an estimate for his income to continue with your return and then go back and enter the real number if you get it before you file. If you file with the estimate, then don’t take the spousal amount, as you may have to pay that back if your estimate was incorrect. You don't need to enter tuition info.
